Thanks again CC and Robert. I called Eddie next-before last Friday at lunchtime, his guy came at 6 that day to take a look, and by last Wednesday (the first convenient time for me) they came and knocked out the whole job, now I too have a 2.5 kilo inverter and 4 batteries, just in time for the electricity games to begin. (And no, they didn't ask for, or get, a peso upfront.)
Do your best JodeSur =you can't touch me now!
